At Mission Dolores and on Monte Diablo (Bolander) ; Cajon Pass and Colorado Valley 

 (Bigelow) ; Salt Lake, Utah ( Watson) ; British America (Drummond) ; and very common 

 throughout Europe and in Asia and Africa. Schimper unites the two species which have long 

 Iteen kept apart upon the variations in the shape of the leaves and in the torsion of the pedicel. 

 The typical form (the F. Hibernica) lias the more attenuate and more acutely serrate leaves, and 

 the pedicel twisted more or less to the left. 



* * Capsule more or less nodding upon an arcuate pedicel ; annulus present. 



3. F. hygrometrica, Hedw. Stems 3 to 10 lines high : upper leaves crowded 

 and connivent, or rarely spreading, broadly ovate-lanceolate, concave, entire, costate 

 nearly to the apex, only the perigonial ones serrate at the apex and base : capsule 

 turgid-pyriform, deep yellow to red, horizontal or pendent upon a flexuous arcuate 

 pedicel | to 3 inches long, deeply sulcate when dry and the very oblique margin 

 corrugated ; operculum broadly convex ; annulus large, at length unrolling. Bruch 

 & Schimp. 1. c., t. 305 ; Wilson, 1. c. ; Sulliv. in Gray's Man. 2 ed. t. 3 ; Berkeley, 

 Brit. Moss. t. 16, tig. 6. 



Var. calvescens, Bruch & Schimp. Pedicel straight : capsule narrower and 

 nearly erect : leaves spreading, rather longer and narrowed, twisted when dry. 

 F. calvescens, Schwaegr. Suppl. t. 65. 



In various localities through the State (Coulter, Bigelow, Pickering, Bolander), and found in 

 nearly all parts of the world. The variety, which is more confined to warm regions, has been 

 collected in American Fork Canon (Brewer), and near Carson City, Watson. 



4. F. microstoma, Bruch & Schimp. Differing from the last in the stouter 

 pedicel, the firmer somewhat shining deep chestnut-colored capsule, only obscurely 

 sulcate when dry, the margin of the much smaller orifice not corrugated, the inner 

 peristome rudimentary, and the spores a half larger. Bryol. Eur. t. 306. 



At Soda Springs, on the Upper Tuolumne (Bolander) ; Illinois ; European. 



5. F. convoluta, Hampe. Loosely cespitose, the stem with the pedicel an inch 

 high : outer leaves spreading with involute margins, the upper convolute and em- 

 bracing the pedicel, oblong-ovate, acute, nearly entire, the costa reaching the apex : 

 capsule ascending, at length nearly erect, obliquely pyriform, more or less plicate ; 

 operculum umbonate, acute : teeth broadly lanceolate, yellowish, the tips incurved. 



- Linnaea, xxx. 455. 



In the Sierra Nevada, at 3,000 to 5,000 feet altitude, J. Bauer. Hampe compares this species 

 with var. calvescens of F. hyc/rometica, from which he differentiates it by the shorter leaves, the 

 smaller and thinner-walled cells, the acute umbonate operculum and the yellowish teeth. It is 

 to be inferred that the capsule is annulate. 



32. LEPTOBRYUM, Schimp. 



Stems low, cespitose, on the ground, simple or innovating from the base, rooting 

 only at base. Leaves numerous, linear-setaceous (the lower much smaller and 

 remote), with broad excurrent serrate costa, areolation linear-rhombic above, smooth 

 and shining. Flowers bisexual ; paraphyses filiform, acute. Fruit as in Eryum ; 

 but the stipitate sporangium much smaller than the cavity of the capsule. 



Only two species, the second Peruvian. 



1 . L. pyriforme, Schimp. Stems } to 1 inch high : leaves soft and green, 

 with silky lustre, spreading, flexuose : capsule inclined or pendulous, ovate-pyriform 

 with long collum and convex apiculate operculum, thin, yellowish brown and shin- 

 ing : ciliolae present. Coroll. Bryol. Eur., and Syu. 2 ed. 390 ; Wilson, Muse. Brit.
